S9KEAZ128A MCU UART0 communication error

Hi, I'm using S9KEAZ128A MCU to communicate with NCK2912 Receiver via UART and getting communication error at 115200 baud rate.

Details on Communication Error as follows -

1. S9KEAZ128A UART0 is initialized to baud rate 115200, after initialization S9KEAZ128A Tx channel is continuously sending the random values.

2. Also from my application sends array of bytes from S9KEAZ128A Tx channel and sent bytes are totally different. Verified the pUART->D register value and its same as what i'm sending from the buffer.

Please help me on this.

Thanks,

Amar#

Problem solved and UART is functioning as expected @115200. Issue is with the External oscillator in my board.
